As best My inventionrelates to cultivators, and shown in Fig. 2, the lever 16 is providedwith an extension or auxiliary lever 21, pivoted between its ends uponthe pivot 17 the upper portion 22 thereof extending up parallel withandadjacent to the lever 16. As shown at 23 in Fig.2, the upper end ofsaid extenhas for its object to provide a new and 1mproved constructionby' which cultivatorshovels may be set to work at any desired depth, butwhich will permit the shovels to be lifted to avoid obstructions, suchlifting,

When released, the gang returns to its normal workingposition, which is regulated by adjusting the lever 16. It

will be apparent also that the raising and lowering of the gang isentirely independent of the lever 16, which may be left in such positionas it previously has been set, so that the working position of the gangmay be maintained constant. If it be desired to relieve the gang fromthe influence of the spring 27 and to control the position of the gangsolely by operating the lever 16, this may be accomplished by placingthe bolt 24 in the holes 26, thereby rigidly connecting the lever withthe extension.

While I have described specifically the embodiment of my inventionillustrated in the drawings, I wish it to be understood that I do notrestrict myself to the details of the construction shown and described,except in so far as they are particularly claimed, but that I claimgenerically the subject-matter of the broader claims.
